I want to dissolve gelma in water based upon this method in order to make a solution and add it to a mold
10% (w/v) gelatin methacryloyl solution was prepared by dissolving the polymer in Mili-Q water under constant stirring at 40 °C. Then, ≈5% (w/w in relation to GelMA) of photoinitiator (Irgacure 2959) was added.
the problem is when we add gelma to water it becomes like a gel so we can't stir it and add the photoinitiator. I am wondering how we can solve this problem
the gelma powder is GelMA, bloom 300, 70–90% degree of substitution, Sigma.
It might look like a gel when it is used in high concentration (> 20wt%). It is better to heat the solution around 50-60 °C if you still have the problem. check this article - Article In situ photocrosslinkable hyaluronic acid‐based surgical gl...
